BA: You will note that Richard Weiss is listed as giving the same talk at two consecutive Potlatches. I vaguely recall that Richard had to cancel his appearance for the ﬁrst of the two listed so that I think the later listing is correct. I undoubtedly have an early announcement in my ﬁles. It is certainly the case that he talked only once.
